DEVICE FOR MOVING ADVERTISING-PLATES, 850.

Application filed May 28, 1906.

Specification 01' Letters Patent.

To all whom it may concern:

Be it known that I, JULIUs ALBIG, a subject of the Emperor of Germany, residing at Spires, Germany, have invented certain new and useful Improvements in Devices for Moving Advertising-Plates, of which the following is a specification.

The present invention has for its object an apparatus intended for the purpose of causing exchangeable displaytables, displaypictures and the like to appear in a striking manner at any desired height by means of visible motion, when a door is opened.

The drawing represents an embodiment of this invention.

Figure 1 shows the entire arrangement seen from in front. Figs. 2 and 3 show details of the mode of securing the display sign. Fig. 4 is a section on line 4-4 of Fig. 1. Fig. 5 shows a modification of the mode of securing the display sign. Figs. 6, 7 and 8 are views of a modification.

Arm 6 is, on one hand, rotatably secured to the door casing c (Fig. 1) and, 011 the other hand, it is shiftably located in the tube a which carries a helical spring d which too, is located in the tube and. which carries at its end a short rod-piece with the binding screw e. By this means the rod 1) may be adjusted in the rod a. Tube a is closed at its other end and rotatably connected by a joint Z, with the sign-holder f. The sign-holder is further connected with the door, by a pivot h secured to the door g.

Part f of the sign-holder, which hangs down when the door is closed and which is intended for holding fast the display-sign i is provided with a longitudinal slit through which pass two pins 2. The display-sign i is provided, for the same purpose, with a flat S shaped projection is adapted to be inserted into the slit of the sign-holder to operatively engage the pins.

It the door is closed, this apparatus, which is secured to the inside of the doors that open inward and which is adjusted to the proper length by means of the binding screw 6, which permits relative adjustment of the free ends of the rods a and 6 without expanding or contracting the spring (1. The parts will occupy the position shown in Fig. 1, while, when the door is opened,the pivotal point of the sign holder is displaced with regard to the pivotal point of the arm 5 and causes the tube a connected with arm l) to be displaced in a direction toward the sign-holder. The pressure thus produced makes the sign-holder turn around the pivot h and the display-sign 01 moves upward until the upper part of the sign-holder f which extends out beyond the pivot it, rests on the tube a, the displayboard being thus caused to occupy the horizontal position adapted for exhibition, see Fig. 2. Any further motion of the door, that may occur, will exert no influence upon the position of the display-board i," such motion will merely compress, to a slight extent, the helical spring (1 located in tube a.

In order to make it possible for the display-plate i to move in an opposite direction, the sign-holder must be bent at right angles, or offset to clear the tube, as shown in Fig. 5 and pivot h, instead of being arranged above the joint Z on tube a, should be arranged as in the part f beneath said joint.

If the moving apparatus is secured to the inside of a door that opens outward, there results a pull exerted against the sign-holder which produces a motion of the displayplate in an opposite direction. In this case a simpler form may be given to the sign holder, (Figs. 6, 7 and 8). The tube (1 takes hold above the pin h. The pull exercised against the sign holder f 3 in opening the door outward, turns it about the pin 72, and the advertising plate t moves upward until it attains a horizontal position, suitable for observation. In this case also, a somewhat wider opening of the door will not alter the position of the raised advertisement plate, but the spiral spring (1 (Fig. 1) in the tube a, will be somewhat extended Lest the advertising sign collide with the door-post while the door is being opened, the spring d is slightly pressed together be fore the binding-screw is screwed tight, so that, while the door is being opened, the spring d is stretched before the sign it begins its upward motion.

The essential feature of the present invention is not merely that the display-plates should occupy a certain position after the opening of the doors, but that the curiosity of the persons who open the door should be excited in a very high degree, by the moverotatably secured to the door and connected ment of said plate. to the other end of the tube a, and a sign I claim: board & removably held in the holder. In combination With a door, and door casi In Witness whereof I have hereunto set my 5 ing, of means operated by the movement of 1 hand in presence of tWo Witnesses.
